Which characteristic is true of a parallel circuit?

In a parallel circuit, one of the defining characteristics is that all components are connected across the same two points of voltage, which means they all share the same voltage. This configuration allows multiple paths for current to flow through each component independently. As a result, while the voltage across each component remains constant and equal to the source voltage, the current through each branch can vary depending on the resistance of each component.

This behavior is opposed to a series circuit, where components are connected in a single path, and thus, the voltage divides among the components. In series circuits, the current flowing through each component is the same, which does not apply in parallel circuits. Additionally, resistance in a parallel circuit is typically less than it would be in a series circuit; as new branches are added, the overall resistance decreases, contrary to what might be inferred from the option about resistance being higher in parallel configurations. Therefore, the assertion that all components share the same voltage directly highlights the nature of parallel circuits.
